Spring中有哪几种方法获取HttpSession对象

Spring MVC

可以直接作为Controller的参数传入：

1. @RequestMapping(value = "/test", method = RequestMethod.POST, produces = "application/json;charset=UTF-8")
2. @ResponseBody
3. public Map test(HttpSession session, String otherParam) {
4. //TODO
5. return null;
6. }

其它

要获取HttpSession，只需要获取到HttpServletRequest，然后调用HttpServletRequest的getSession方法

1、注解自动注入

1. @Autowired
2. private HttpSession session;
4. @Autowired
5. private HttpServletRequest request;

2、普通类中获取

1. HttpServletRequest request = ((ServletRequestAttributes) RequestContextHolder.getRequestAttributes()).getRequest();
3. request.getSession();
